# Roblox Performance Analysis: AMD Ryzen 7 9700F + NVIDIA GeForce RTX 5070

The AMD Ryzen 7 9700F paired with the NVIDIA GeForce RTX 5070 delivers exceptional frame rates across all tested resolutions and settings in Roblox, with measured average FPS ranging from 132 at 4K Ultra to 537 at 1080p Low. The combination ranks 603rd out of 3,010 tested combos, placing it in the top 20% of all configurations evaluated for this game. This analysis breaks down the measured performance data to identify optimal settings, component bottlenecks, and scaling behavior.

Settings Recommendations

The measured FPS data reveals that the Medium preset offers the best balance of visual quality and performance across all three resolutions. At 1080p Medium, the combo achieves 489 average FPS with a minimum of 415 and maximum of 562, representing a 9% reduction from Low settings (537 FPS) while providing substantially better visual fidelity. The 1440p Medium result of 326 average FPS (minimum 277, maximum 375) maintains a comfortable margin above display refresh rate capabilities, while 4K Medium delivers 184 average FPS with a 157 minimum, ensuring smooth gameplay even in demanding scenes.

For users prioritizing maximum visual quality, the Ultra preset remains viable at every resolution. At 1080p Ultra, the system produces 350 average FPS, dropping to 234 at 1440p and 132 at 4K. These figures indicate that even the most demanding settings configuration stays well above the 60 FPS threshold typically considered the minimum for smooth gameplay. However, the step from Medium to Ultra costs 139 FPS at 1080p (489 to 350), 92 FPS at 1440p (326 to 234), and 52 FPS at 4K (184 to 132), making Medium the recommended choice for competitive play where high frame rates provide a tangible advantage.

The Low preset, while delivering the highest frame rates (537 at 1080p, 358 at 1440p, 203 at 4K), sacrifices too much visual quality for the marginal FPS gain over Medium. The data indicates that Roblox's visual presentation benefits significantly from the Medium settings tier, and the performance headroom available with this hardware combination makes the Medium preset the clear recommendation for most users.

GPU Role

The NVIDIA GeForce RTX 5070, built on the Blackwell 2.0 architecture with a 5 nm process, brings substantial graphics capabilities to Roblox. The GPU features 12 GB of GDDR7 memory on a 192-bit bus, providing 672.0 GB/s of memory bandwidth. The 6,144 shading units, 192 texture mapping units, and 80 render output units process geometry and pixels efficiently, while the 48 RT cores and 192 tensor cores handle advanced rendering features.

The GPU's clock behavior shows a base frequency of 2325 MHz with a boost up to 2512 MHz, and memory operates at 1750 MHz (28 Gbps effective). These specifications translate to a pixel rate of 201.0 GPixel/s and a texture rate of 482.3 GTexel/s, with FP32 compute reaching 30.87 TFLOPS. In Roblox, the GPU's role becomes increasingly important at higher resolutions and settings, as evidenced by the performance scaling from 1080p to 4K.

The measured FPS data demonstrates that the RTX 5070 handles Roblox's rendering requirements with substantial headroom. Even at 4K Ultra, the most demanding tested configuration, the GPU maintains 132 average FPS. The GPU's 82nd percentile ranking among all GPUs and its benchmark scores (29,137 in Passmark G3D, 15,787 in Passmark GPU Compute) indicate strong overall performance that translates well to Roblox's relatively modest graphics demands compared to AAA titles.

CPU Role

The AMD Ryzen 7 9700F serves as the central processor for this combination, featuring 8 cores and 16 threads based on the Zen 5 architecture (Granite Ridge). The CPU operates with a base clock of 3.80 GHz and boosts up to 5.50 GHz, with a 65 W TDP. The 8,315 million transistors on a 70.6 mm² die, manufactured on TSMC's 4 nm process, provide substantial computational throughput.

The CPU's 32 MB shared L3 cache and 1 MB L2 cache per core facilitate efficient data access for game logic and physics calculations. Memory support includes DDR5 with dual-channel configuration and 89.6 GB/s bandwidth, ensuring the CPU can feed the GPU with data without bottlenecks. The Passmark scores demonstrate strong single-thread performance (4,691) and multithread capability (36,470), with the 94th percentile ranking among all CPUs confirming its high-end positioning.

In Roblox, the CPU's role is particularly significant at lower resolutions where the GPU can render frames quickly. The 1080p results show the CPU's influence: at Low settings, the system reaches 537 FPS, suggesting that the CPU's single-thread performance becomes the limiting factor at extreme frame rates. The jump from Low to Medium at 1080p (537 to 489 FPS) indicates that while the GPU handles additional graphical work, the CPU maintains sufficient throughput. The CPU's nearest rivals include the AMD Ryzen 9 7940HX (0.2% faster), Intel Core i7-14700KF (0.2% slower), AMD Ryzen 9 7950X (0.7% faster), and Intel Core i7-14700K (0.9% faster), showing this processor sits in a tightly contested performance bracket.

Resolution Scaling

The measured FPS data reveals distinct scaling patterns as resolution increases from 1080p to 4K. At Medium settings, the system delivers 489 FPS at 1080p, dropping to 326 FPS at 1440p (a 33% reduction) and 184 FPS at 4K (a 62% reduction from 1080p). This scaling pattern indicates that the GPU becomes progressively more stressed at higher resolutions, though the absolute performance remains high throughout.

The High settings show similar scaling: 432 FPS at 1080p, 288 FPS at 1440p (33% reduction), and 163 FPS at 4K (62% reduction). The Low preset exhibits the steepest relative decline: 537 FPS at 1080p, 358 FPS at 1440p (33% reduction), and 203 FPS at 4K (62% reduction). The Ultra preset follows the same proportional pattern with 350, 234, and 132 FPS respectively.

The consistent percentage reduction across settings suggests that the scaling behavior is primarily resolution-driven rather than settings-driven. The 33% drop from 1080p to 1440p and 62% drop from 1080p to 4K (for each settings tier) indicates the GPU's fill rate and pixel processing capabilities are the primary determinants of performance at higher resolutions. The CPU's influence diminishes as resolution increases, with the GPU taking on a larger share of the rendering workload.

Measured FPS Breakdown

At 1920x1080, the system produces its highest frame rates across all settings. The Low preset achieves 537 average FPS, representing the maximum measured performance. Medium settings yield 489 average FPS with a minimum of 415 and maximum of 562, providing a 48 FPS reduction from Low. High settings deliver 432 average FPS, while Ultra produces 350 average FPS. The spread from Low to Ultra at 1080p is 187 FPS, demonstrating the significant performance cost of higher graphical settings.

The 2560x1440 results show consistent scaling from the 1080p figures. Low settings produce 358 average FPS, Medium delivers 326 (minimum 277, maximum 375), High achieves 288, and Ultra reaches 234. The settings spread at 1440p is 124 FPS, narrower than at 1080p, indicating the GPU's workload increases as resolution rises, compressing the performance differences between settings tiers.

At 3840x2160, the system maintains impressive performance despite the four-fold increase in pixel count from 1080p. Low settings achieve 203 average FPS, Medium delivers 184 (minimum 157, maximum 212), High produces 163, and Ultra maintains 132. The settings spread at 4K is 71 FPS, the smallest of all resolutions, showing that the GPU becomes the dominant performance factor at this resolution and settings choices have less relative impact.
